A lentigo is a pigmented flat or slightly raised lesion with a clearly defined edge.

Lentigos are primarily caused by sun exposure. Over the years, damage from the sun can cause pigmentation deposits in the skin which creates lentigos.

Sunscreen is a great tool to prevent lentigos from forming. To get rid of these brown spots, there are a few options. Chemical peels are a great way to remove the layer of skin that is hyperpigmented and reveal skin that hasn't been damaged by the sun. Prescription creams from a dermatologist can also lighten these dark spots.
